CVE-2024-36144 in Experience Manager
Summary
by MITRE • 06/13/2024
Adobe Experience Manager versions 6.5.20 and earlier are affected by a stored Cross-Site Scripting (XSS) vulnerability that could be abused by an attacker to inject malicious scripts into vulnerable form fields. Malicious JavaScript may be executed in a victim’s browser when they browse to the page containing the vulnerable field.

Adobe Experience Manager suffers from a critical stored cross-site scripting vulnerability that fundamentally compromises user session integrity and application security. This flaw exists within the content management system's form handling mechanisms where user inputs are not properly sanitized before being stored and subsequently rendered back to users. The vulnerability specifically affects versions 6.5.20 and earlier, indicating a widespread impact across the AEM 6.5.x release line that has been maintained for several years. When attackers exploit this weakness, they can inject malicious javascript code into form fields that persist in the application's database or storage mechanisms. The stored nature of this vulnerability means that the malicious payload remains active even after the initial injection, making it particularly dangerous as it can affect multiple users over extended periods. The vulnerability aligns with CWE-79 which categorizes cross-site scripting flaws as weaknesses in input validation and output encoding. From an operational perspective, this vulnerability creates a significant attack surface for threat actors seeking to compromise user sessions, steal sensitive data, or redirect victims to malicious domains. The impact extends beyond simple script execution as it can enable more sophisticated attacks such as credential theft, session hijacking, and data exfiltration through browser-based exploitation techniques. The attack vector requires minimal privileges as the vulnerability can be exploited through normal form submission processes, making it accessible to both authenticated and unauthenticated attackers depending on the specific implementation details. This vulnerability directly maps to attack techniques described in the attack tree under the web application attack pattern category where persistent XSS serves as a foundational primitive for more complex exploitation chains. Organizations utilizing AEM 6.5.20 or earlier versions face immediate risk of user compromise and data breaches, particularly in environments where sensitive content management operations occur. The persistent nature of stored XSS makes this vulnerability particularly challenging to detect and remediate, as malicious scripts can remain dormant in the system for extended periods before being triggered by unsuspecting users. The technical flaw represents a failure in the application's security input validation controls, specifically the absence of proper sanitization of user-supplied content before persistence. This vulnerability demonstrates the critical importance of implementing robust content security policies and proper output encoding mechanisms that align with industry best practices established in OWASP Top 10 and NIST cybersecurity guidelines. The risk assessment for this vulnerability should consider the potential for privilege escalation, data leakage, and the establishment of persistent backdoors through browser-based exploitation techniques that leverage the stored nature of the vulnerability.
The exploitation of this stored XSS vulnerability creates multiple operational security implications for organizations relying on Adobe Experience Manager. The vulnerability can be leveraged to execute arbitrary javascript code in the context of a victim's browser session, potentially leading to complete compromise of user accounts and sensitive content access. Attackers can craft malicious payloads that appear legitimate to end users, making detection more challenging through traditional security monitoring approaches. The vulnerability's impact is amplified in enterprise environments where AEM systems often manage sensitive customer data, proprietary content, and business-critical applications. From a compliance perspective, organizations may face regulatory violations under frameworks such as gdpr, hipaa, and soc 2 if this vulnerability is exploited to access or exfiltrate protected data. The attack scenario typically involves an attacker submitting malicious content through a form field, which is then stored in the application's backend. When other users navigate to pages containing these vulnerable fields, their browsers execute the injected javascript code, potentially capturing cookies, credentials, or redirecting to malicious sites. This vulnerability directly relates to the attack pattern identified in the mitre attack framework under the web application exploitation category, specifically targeting the application layer where user inputs are processed. The remediation strategy should prioritize immediate patching of affected AEM versions, implementation of comprehensive input validation controls, and deployment of web application firewalls with XSS detection capabilities. Organizations should also implement proper security monitoring to detect anomalous user behavior patterns that may indicate exploitation attempts. The vulnerability highlights the importance of maintaining up-to-date security practices and the risks associated with running unsupported software versions that may contain known security flaws. Security teams must also consider implementing content security policies and proper output encoding to prevent similar vulnerabilities from emerging in custom-developed applications that integrate with AEM. The long-term implications of this vulnerability underscore the necessity of comprehensive security testing and vulnerability management programs that can identify and remediate such flaws before they can be exploited by threat actors.
